Update Galaxy A3 A300H to XXU1AOA4 Android 4.4.4 Official Firmware

Samsung Galaxy A3 A300H has started receiving the latest Android 4.4.4 XXU1AOA4 update. This firmware shows Samsung is keen to keep the A series up and well. Not only is XXU1AOA4 Android 4.4.4 the very first firmware update in the year 2015 but it brings new tweaks and enhancements as well. However, it doesn’t include anything which can be considered major. We are hoping to see the Android 5.0 Lollipop firmware arrive very soon. Till then, you can enjoy Android 4.4.4 KitKat which is good combined with TouchWiz UX. As per tradition, XXU1AOA4 Android 4.4.4 firmware can be acquired through official Samsung KIES software while some users in supported areas will be getting OTA (Over-the-air) updates straight on their phones. Fortunately, we have an option available for users who cant find the update, that is, manually updating your Galaxy A3 via our tutorial. You can easily update Galaxy A3 A300H to XXU1AOA4 Android 4.4.4 KitKat official firmware– and also root Galaxy A3 A300H phone on this firmware. A300HXXU1AOA4 is a complete unbranded firmware, which means you should not get any pre-installed apps or extra language packs with this.

If you update your Samsung Galaxy A3 using Samsung KIES, then a backup is not always necessary and there are less chances of anything going wrong. However, we recommend that you always backup your stuff and all your apps, because you never know when something might happen to your phone while manually flashing firmwares.

Backup and Other Important Tips

Done with the USB drivers? Perfect. The tutorial is on the next page, but first, please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps:

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:

Samsung users can also back up data using Samsung KIES. If you backup data manually, you get more options what to choose from and it is very easy to move data across Android devices from different manufacturers, i.e moving Samsung Galaxy Note backup data to HTC One X.

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.

A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, KitKat and Lollipop.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.
